Ex-Merrimack, Seragon Execs’ New Startup Gets $60M, Buys Sanofi Drug

Partner Therapeutics, a Boston startup launched last week by a pair of former Merrimack Pharmaceuticals and Seragon Pharmaceuticals executives, has raised $60 million and acquired an immune system-boosting drug from Sanofi for an undisclosed sum.

Perceptive Advisors, Adams St. Partners, and MidCap Financial, meanwhile, led the $60 million Series A for Partner, which aims to buy up late-stage or marketed cancer drugs from others and develop them for different cancers or related afflictions.
